IMPROVEMENT 1N PAnLocKs.

The Schedule referred to in these .Lettersv Patent and making part of the same.

To all whom fit may concern Be it known that I, HENRY F'. HAACK, ot' the city, county, and State of New York, have invented a new and improved Padlock and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make andv use the same, reti-rence being had to the' accompanying drawing forming part of this specification, in which- Figure l represents a face vView of my improved padlock, showing it locked.

Figure 2 is .a face view-of the same, showing it unlocked.

Figure 3 is a side view of the key. Similar letters of reference indicate corresponding parts.

My invention relates to that class of padlocks whose tumblers are operated by pushing a flat key against them; and

The invention consists v,in the arrangement of the locking-dog so as to lock into the hasp from the' front side, and having tumblers pivoted thereto at ,its lower extremity, in. combination with; a stationary stop, as hereinafter specified.

A, in the drawing, represents the case or shell ot the lock. A

B is the ball or link of the same.

C is. the bolt, pivoted to the lock-case by a pin, a, and providcdwith a hook, l1, which locks intothe notched or perforated end ot the bail, as in g. 1.

D D are the tumblers.

They are, by a pin, c, pivoted to the surface of the bolt, and are slotted to work on apn, (l, that projects from the lock-case, as shown. Theslot-s in the tumblers are nearly T-shaped.

lhe springs e hold the tumblers in thepositioul shown in lig. 1, in which the pin d is in the upper end of ltheir slots, thereby preventing the bolt to When the key E is inserted throngha-slot in the side ot the lock-case, it strikes first against the tumblers and raises them so as to bring the arms f ot' their slots into line with the pin d.

The parts f o't' the slots are all on a circle described around the pin (t. The key can now more when it reaches the bolt, swing the same on its pivot a, and draw its hook od' the link B.

As soon as the link B is liberated from the4 bolt it is thrown open by a spring plate,1*,pivoted in the lock-case.

This s rin late has also Aa roeetin ear w-iiichv a I) u 1 v arrests the boltas in g.2, keeping the'sl-me in such a. positionthat the device will be self-locking.

The end of the link, when forced into the lock, will come between the ear g and the end of the hook l), pushing both aside and descending into the lock.

As soon as the aperture or recess of the link ar` rives in line with the hook b, the latter is, by the boltspring h, forced int-o such aperture or recessto lock the link.

The peculiar characteristic of this lock consists in the arrangement of the tumblers upon the bolt-,-and in the combination of thoseparts" with the spring plate F.

I wish to be understood as making no claim broadly to the combination of a stationary stop, pivoted tuniblers,and dog; but

Haring thus described my invention',

I claim as new and desire to secure by Letters Patento A padlock having a locking-dog, C, pivoted centrally, and arranged tolock into the hasp from the front side, with the tumblers D pivoted thereto at its lower extremity, in combination with .the stationary stop d, all as set forth and shown. f
